Abstract
A vehicle propulsion system comprising a plurality of solid state rechargeable battery cells configured to power a drivetrain. In accordance with once aspect of the invention, a transportation system that is powered at least in part by electricity stored in the form of rechargeable electrochemical cells. According to an embodiment of the present invention, these cells are combined in series and in parallel to form a pack that is regulated by charge and discharge control circuits that are programmed with algorithms to monitor state of charge, battery lifetime, and battery health.
